Top 5 Tax Strategies to Minimize Taxes Before and During Retirement (2026 Guide)

If you’re within 5–10 years of retirement, taxes become one of the biggest threats to your income plan.

The difference between a smart filing strategy and a reactive one can mean tens of thousands of dollars saved over the next decade — especially as Required Minimum Distributions (RMDs), Medicare premiums, and Social Security taxation all collide.

Here are the Top 5 Tax Strategies to consider as you file your 2025 return and position yourself for retirement.

1. Strategic Roth Conversions Before RMD Age

If most of your savings are in:

• Traditional IRAs

• 401(k)s

• SEP IRAs

You’re sitting on a tax-deferred time bomb.

Once you reach RMD age (currently 73 under the SECURE 2.0 rules), the IRS forces withdrawals — whether you need the income or not. That can:

• Push you into a higher tax bracket

• Increase taxation of Social Security

• Trigger IRMAA Medicare surcharges

Strategy:

Convert portions of your IRA to a Roth IRA in controlled amounts while your tax bracket is lower (often between retirement and RMD age).

You pay taxes now — potentially at a lower rate — to create tax-free income later.

2. Capital Gain Harvesting (When Your Income Is Lower)

Many retirees experience a “tax valley” between:

• Retirement

• Social Security start

• RMD start

During this window, you may qualify for 0% long-term capital gains tax.

Strategy:

Sell appreciated assets intentionally to:

• Reset cost basis

• Lock in gains at lower rates

• Reduce future tax exposure

This is especially powerful for brokerage accounts holding stocks, land, or mutual funds.

3. Qualified Charitable Distributions (QCDs)

If you are age 70½ or older, you can use a QCD from your IRA.

Instead of:

• Taking an RMD

• Paying tax

• Donating after-tax dollars

You can send money directly from your IRA to a qualified charity.

Benefits:

• Reduces taxable income

• Satisfies RMD requirements

• May lower Medicare premium exposure

This is one of the cleanest ways to give — and lower taxes at the same time.

4. Maximize Catch-Up Contributions (While You Still Can)

If you’re still working and over age 50:

You qualify for catch-up contributions in:

• 401(k)s

• IRAs

• HSAs

This allows you to:

• Reduce current taxable income

• Build more retirement capital

• Create flexibility in future tax brackets

If you are in peak earning years right before retirement, this may be one of your last chances to aggressively reduce income.

5. Coordinate Social Security Timing With Tax Brackets

Up to 85% of Social Security benefits can become taxable depending on total income.

The mistake many retirees make:

They claim benefits without evaluating how it stacks with:

• IRA withdrawals

• Pension income

• Capital gains

• Rental income

Strategy:

Run coordinated income projections before filing and before claiming benefits.

Sometimes delaying benefits:

• Reduces lifetime tax burden

• Increases survivor income

• Lowers bracket stacking in early retirement years

This is especially important for married couples due to the “widow’s tax” — where the surviving spouse files single and often jumps brackets.

Bonus Strategy: Don’t File in Isolation

Your CPA prepares returns based on what happened last year.

A retirement-focused tax strategy looks forward:

• What bracket will you be in at 73?

• How large will your RMDs be?

• Will Medicare premiums increase?

• How will your surviving spouse be taxed?

Tax preparation and tax planning are not the same thing.

Final Thought

The goal isn’t just to minimize taxes in 2025.

The goal is to minimize lifetime taxes.

That requires:

• Coordinated withdrawal planning

• Strategic bracket management

• Proactive Roth positioning

• Income timing discipline

If you’re within 10 years of retirement, this is the window where smart decisions can permanently improve your financial future.
